WINDOW-SCREEN.

SPECIFICATION forming part or Letters Patent'No. 739,592, dated September 22, 1903.

Application filed April 27, 1903. $erial No. 154,447. (No model.)

To ztZZwhom it may concern:

Be it known that I, J OHN EMERICK ELMEN- DORF, of the city, county, and State of New York, have invented certain new and useful Improvements in Nindow-Screens, of which the following is a fuli, clear, and exact description. I I

My invention relates to improvements in windowscreens; and the main object of my invention is to produce'a simple formof adjustable screen which will project from the window so as to form a screened recess. This, it will be seen, enables a person to thrust his head from the window and look through the screen up and down the street, which cannot.

be done with an ordinary flat window-screen.

Furthermore, by projecting the screen asherein described the air-currents are caught and deflected into the building through the window-openin g, a better ventilation is therefore afiorded, and the receptacle formed by the projecting screen serves to receive articles which it may be desired to keep cool or which may be placed therein to air-'as, for instance, bedclothing;

Other objects of my invention are to construct the screen in a simple and substantial manner and yet in such a way as to make it adjustableto windows of somewhat varying width, to the end that itmay easily be placed in position and fitted.

Still other objects are to construct and arrange the several parts so that the screen can be easily and securely fastened in place and so that it will be durable and will generally serve the purposes of a well-ventilatingscreen.

lVith' these and other objects in view my invention consists of certain features of construction and combinations of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification,

in which similar figures of reference refer to easily pushed through these ways and will similar part-s throughout'the several views.

Figure 1 is a front elevation of'my improved screen as applied to a window. Fig. 2 is a plan view of the same. Fig. 3 is a detail section on the line 3 3 of Fig. 2. Fig. 4. is a broken vertical section showing the arrangement of one of the side posts or rods of the screen. Fig. 5 showsaform of binding strip or clip for attaching the screen-bodyto one 'of the supporting-posts. Fig. 6 is a detail section on the line 66 of Fig. 4. Fig. 7 is a broken detail perspective of a form of binding-clip. Fig. 8 is a plan View showing a modified form of the screen, and Fig. 9 'is a plan view illustrating still another modification of the screen.

In carrying out my invention the main ob ject is to produce a simple form of projecting screen, and while I shall describe a preferred means of carrying this object into efiect,still I do not limit myself to the precise'construction which I have shown.- The preferred form of screen is triangular in cross-section, as shown by theplan in Fig. 2, and it comprises two side members of the screen, which are secured to the side posts or rods on the windew-frame and which are *hi'nged at their meeting points, so that the screen mayt'hns be readily adjusted to fit any usual widthof window. To this end the screen is provided with supporting side posts 10, which have near the upper and lowerends shoulders 1O andwhich' carrylthe screen proper; 12. The screen-bodyjis' connected with the side post bymeans of suitable strips or clips 11, which are bent so as to fit the posts 10, and the op-v posite side portionsof which are squeezed or clamped to the screen. Hereinafter I shall refer to several means of elfecting this fastening. Obviously the side rods or posts 10 may besupported in several ways; butIprefer to use the socket-brackets 13, which are fas tened at points adjacent to the top and bot-. tom of the screen to the window-frame 14, the socket brackets having for this purpose bracket-plates 15, which fit against the sides of the frame 14 or other suitable support.

In order that the side post may be held tightly and yet easily pushed to place, the upper and lower sockets 13 are provided with inclined ways 16, (see Fig. 6,) which terminate in seats 16, and the posts 10 may be then squeeze into their seats 16, where they will rest securely. Instead of having both upper and lower sockets provided with the IOI The opposite sides of theclips or bindingstrips 11 may be fastened in several ways. For instance, one may be provided with a slot 17,the other may have a lug 18 struck up from it, as in Fig. '7, and when the parts are pushed togetherthelug may be thrust through the slot and clenched. To get a good grip on the screen 12 or the top and bottom screen 12, presently referred to, the clip 11 may be corrugated, as at 19 in Fig. 6, orthe corrugations may extend longitudinally of the clip, as at 19 in Fig. 3. These binding-strips are used on the side edges and top and bottom of the screen, as will presently appear.

The'meeting side portions of the screen are connected at the center by meansof strips 20, which have hinge-knuckles 21 formed on them, through which runs an ordinary pintle having nuts 22 at top and bottom. The strips 20 are like the strips 11 in that they are corrugated either at 19 or 19, so that they shall have the right grip on the screening. Thus it will be seen that the screen may be bent or pushed in or out in the center, so that the sides may be conveniently fastened without regard to the width of the window. The object of the nuts 22 is to prevent the displacement' of the pintle and also to bind in place the rods 24, which extend from the rods 10 to the central pintle at the top and bottom of the screen, the ends of the rods being formed into suitable hooks, as shown in the drawings, (see Figs. 1 and 4,) to extend around the pintle and the rods 10.

The bottom and top of the screen are substantially alike, being formed of the rods 24, just described, and a rod 23, which extends straight across the window-frame, the ends of the rods 23 engaging the rods 10 near the shoulders 10, as shown in Figs. 2 and 4. The socket-brackets 13 should be adjusted in relation to the window-sashes so that the crossrod 23 shall be flush against the bottom of the upper sash, thus rendering the screen insect-proof. The rods 23 and 24 are provided with suitable binding strips or clips 11, substantially like those already described, except that the clips on the outer edges of the top screen 12 are squeezed together and formed into hooks 11 adapted to engage the clips 11 on the rods 24, as shown clearly in Fig. 3. Thus all the parts of the screen are conveniently and securely fastened together, and they can be easily adjusted. In placing the screen in the window the socket-brackets 13 are first secured at the necessary points, the rods 23 and 24 of the top are placed in engagement with the side rods 10, the upper ends of the latter are inserted in the top brackets 13, the bottoms of the rods 10 are then brought close to the lower brackets 13, and the lower rods 23 and 24 are placed in engagement with the lower ends of the rods 10 when the latter are pushed to their seat, and the whole screen is thus in position for use. It will be seen that a projecting or balcony screen is thus formed in which any articles can be placed which it is desirous to keep cool and that perfect ventilation is afforded.

I do not limit my invention to the triangular form of screen described, as many modifications may be used. For instance, the screen may be bowed out in the form of a cylinder-section, as in Fig. 8, or it may be carried out as in Fig. 9, where it has a flat outer face and two hinge-pintles instead of one.

.Likewise other projecting forms may be devised without departing from the principle of the invention.

It will be seen that by providing a projecting screen, and especially one with the inclined sides, I am able. to divert the air-currents so as to enable them to enter forcibly into a room,and thus thoroughly ventilate and cool the same. I also wish to call attention to the fact that, if desired, the brackets 13 may be placed as far apart as need be-as, for instance, near the top and bottom of the Window-and the rods 10 made long enough so that the whole screen may be pushed up or down, so as to cover any part of the window open.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A window-screen comprising two main body portions hingedat their meeting edges, fastening devices for securing the said body portions to a window-frame, and a suitable top and bottom of screening adapted to be fastened to the window-frame and the body portions and form the top and bottom of the screen, the said top and bottom being at substantially right angles to the plane of the body portion of the screen.

2. A window-screen comprising two main body portions having their meeting edges provided with engaging hinge-knuckles, fastening-rods to secure the side edges of the screen-body to a window-frame, suitable sockets to receive the rods, said sockets being adapted for attachment to the window-frame, and top and bottom sections secured to the side rods and adapted to close over the top and bottom respectively of the screen.

3. A windowscreen, comprising hinged body portions, vertically-arranged side rods secured to the edges of the body portions,

sockets adapted to be fastened to a windowframe and to engage the side rods, and top and bottomscreen-sections connected to the side rods and adjustably fastened to the hinged portion of the screen.

4. A window-screen, comprising two main body portions hinged at their meeting edges, supporting-rods secured to the sides of the screen, sockets adapted to engage the supporting-rods and to be fastened to a windowframe, and top and bottom screen-sections, said sections havingat their edges rods which are adapted to engage the side rods of the screen and the hinge-pintle.

5. The combination with a projecting windew-screen, of rods secured to the edges disposed sections hingedto'one another, and on the extreme outer edges to the windowframe, and horizontal top and bottom portions.

8. A window-screen comprising rectangular body portions pivotally arranged in relation to one another whereby the distance between the extremes can be regulated, means for pivotally securing the extreme edges to a window-frame whereby the frame can be fitted'to difierent sizes of windows, a removable top porti0n,and aremovable bottom portion.

In testimony whereof I have signed my name to'this specification in the presence of two subscribing witnesses.
